More About This Title Principles of Turbomachinery
English
Key features:
Combines theory and applications to show how gas turbines, pumps and compressor function
Allows for a smooth transition from the study of thermodynamics, fluid dynamics, and heat transfer to the subject of turbomachinery for students and professionals
- Relates turbomachinery to new areas such as wind power and three-dimensional effects in axial turbomachines
- Provides information on several types of turbomachinery rather than concentrating specifically on one type such as centrifugal compressors
